HEEL-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 410,676, datedSeptember 10, 1889.

(No model.)

To 0% whom it may concern.-

Be it known that I, FREEBORN F. RAYMOND, 2d, of Newton, in the county ofMiddlesex and State of Massachusetts, a citizen of the United States,have invented a new and useful Improvement in Nail Distributing andDriving Machines, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification, in explaining its nature.

The invention relates especially to an automatic device or mechanism forfeeding nails from tack-strips, or nails whose heads are integral orconnected by paper or any other medium to a distributer.

It further relates to the combination of said feeding and distributingmechanism with nail-driving devices.

It also relates to various details of organization and construction, allof which will hereinafter be specified.

In the drawings, Figure 1 is a view in rear elevation of a naildistributing and driving machine containing the features of myinvention. Fig. 2 is a view thereof in vertical central section. Fig. 3is an enlarged View, part in rear elevation and part in Verticalsection, of the nail-distributing mechanism. Fig. 4 is a horizontalsection on the line 00 0c of Fig. 3 of that part of the mechanismadjacent to the throat of the device. Fig. 5 is a detail view toillustrate the start-and-stop-motion mechanism of the nail-distributingdevices. Fig. 6 is an elevation and vertical section of the partsrepresented in Fig. 3, and at a right angle to the view therein shown.Fig. 7 represents an enlarged view, in perspective, of a comb-strip offastenings. Fig. 8 is a view in perspective of a nail or fasteningsevered therefrom.

The invention is represented as organized to supply nails to a heel orsole nailing machine; but this form of nailing-machine is shown merelyfor convenience, the invention being applicable to any machine adaptedor arranged to drive a gang or group of fastenings.

The principal parts of the nail-driving devices are described in myLetters Patent No. 1,169, and I will but briefly enumerate those partshere. A is the frame of the machine.

B is a short shaft which carries the crank 11, which operates thereciprocating Verticallymovable head 0 by means of a slide-block c.

Below the reciprocating head 0 there is another head C', which supportsa gang or group of drivers D. This head O is moved downward by means ofthe slide-block d, which is arranged to be moved between the head 0 andthe head 0 when it is desired to reciprocate the drivers, and the head 0is moved upward by a spring (1'.

E is the templet-plate. e is the last or worksupport,which is mountedupon a jack 6. The templet-plate is supported by the table 6 and has adownward vertical movement in opposition to the springs'c? The tablecarries or supports a nail-carrier a which is automatically moved from aposition under the nail-distributer F to a position to deliver nails tothe drivers and holes of the templet E by mechanism substantially asspecified in said patent, and comprising two links or toggle, one linkof which is pivoted to the table and the other to the nail-carrierplate, a bent lever, one arm of which is connected by a link with thetoggle and the other of which is connected with a slide, moved by thecam 62 formed in a projection or extension of the head C. This cam isshaped to move the nail-carrier inward upon the downward movement of thehead 0 and outward upon the upward movement of the head, and so that itshall be moved into position to bring its holes in line with the holesof the templet, and while the drivers are upon the upward part of theirdownward movement, and to then hold the carrier stationary, that thedrivers may enter the holes and drive the nails therefrom into the work,and be lifted from the holes before the carrier is returned to itsoriginal position. The head 0 may of course be connected with the head Cby a yoke or strap and pin, or in any other desired way, so that thehead 0 shall act to draw the head 0 up positively, if desired. Thedistributer F comprises a block f, having the holes f, of the samearrangement as the holes of the nail-carrier, which are adapted to beclosed when the nail-carrier is moved from the block f by a slide-platef. A series of tubes f connect the holes in the block f with the holes fin the block f. The holes in the block f are arranged in a straightline. Thus far the mechanism described is like that described in saidpatent.

To automatically supply the nail-driving devices with fastenin gs, Ihave mounted above the plate f a traveling block G, which carries orsupports a device for feeding a comb or nail-strip to a reciprocatingpunching or severing device or instrument. This traveling block G has ahole or throat g, which is adapted to be brought in line, as the block Gis moved, in successive order with the holes g in the block f The blockG is provided with an intermittent forward movement from one hole toanother, and is held stationary during the feeding movements and whileafastening is being delivered to ahole g by a detent. At the end of theforward feeding movement the block, with the nailfeeding devices carriedthereby, is returned to it's original position.

I have represented the nail plate or strip separate int-o independent orseparate fastenings a eomb-strip of nails, such as is described in mypatent, No. 315,069; butI would say that it is also applicable forfeeding the tack or nail strip known as the Copeland tack or nail strip,such as is described in Patents Nos. 197,609 and 833,709, or any nail Aor tack strip of a similar character.

- The mechanism which I have shown for feeding the comb-strip and forsevering com.- plete or single nails therefrom comprises a feed-pawl'g(see Figs. 3 and 4,) which is supported by a block 9 arranged to bereciprocated by means of the lever pivoted at g, and thevertically-movable cam g formed in the driver-block and connected withthe lever g by the push-rod or slide 9 The feed-pawl g is formed from athin plate of steel, so as to yield horizontally upon its backwardmovement to clear the shank of a nail or tack and then close behind it,and it feeds the strip forward to the throat by contact with the edge ofthe shanks. It is arranged to project into the feedway 9 as representedin Fig. 4.

To hold the comb-strip or strip of tacks or fastenings after it has beenfed forward by the feed-pawl 9 I have arranged a detent or spring-stopg", (see Fig. 4,) to close into the feedway and behind the shank of anail or tack. This is also made of spring-steel and so shaped orfastened as to yield outwardly on the forward movement of the stripas-it is fed by the feed-pawl g as the shank of a nail or tack comes incontact therewith, and to automatically close behind said shank after ithas been moved by it into the throat At theend of each forward movementof the strip of fastenings the first or advanced fastening is cut orsevered from the remainder of the strip by the severing device orplugger H,which is arranged upon the plungerbar L.

a post h, extendingupward from the travel- This plunger-bar has asupport within ing blockG, to which it is bolted, and it has a head 71and a coil-spring 71 which surrounds said plunger-bar above the post hand bears against the upper surface of the latter and the under surfaceof the head 71 There is arranged immediately above the line upon whichthe head It travels a long wiper-cam M, which is mounted upon the shaftm, and the office of this cam is to depress or move downward theplunger-bar h in opposition to the spring 72. The cam M is made longenough to embrace or include the entire movement of the traveling blockG, so that whatever the position of the block the plunger upon therotation of the cam is caused to be moved downward. The shape of thiscam in section is well represented in Fig. 2. The shaft on also carriesthe cam-cylinder m, which has the cam-groove m which serves to operatethe feed-pawl m and the stop-motion mechanism, and it is connected withthe feedpawl by the lever m, which is pivoted at m and with the drivenpulley m forming one member of a clutch, by means of the latchbar m andswinging rod m which is pivoted at m, and which has a yoke that engages,by means of pins, the hub of the driven pulley m. The traveling block Galso carries a trippingblock N, which is adjustable upon its side totrip the detent n and feed-pawl when any desired number of fasteningshave been delivered through the throat g, and the detent 'n has aprojection n, with which the block N comes in contact as the travelingblock G is moved by the feed-pawl. These blocks N n are so shaped thatupon coming in contact with each other the detent n is lifted fromengagement with the ratchet-teeth n of the traveling block, and it inturn serves to lift the feed-pawl m from contact with the ratchet-teeth,the arm of the feed-pawl having a pin or stud "a which projects over thedetent- .arm, and so as to be moved thereby upon the upward movement ofthe said arm. The upward movement of the detent-arm also brings intoposition the stop-motion latch m by moving outward or away from thesection a of the said arm the arm n of the detent, which serves to holdit lifted, while the detent acts .as a stop. When the detent is movedupward, however, the arm n is moved from the surface a", so that the armn is free to move downward-to permit its shoulder a to engage theprojection nlupon the lever m and this permits the cam m upon itscontinued movement, to move backward or disengage the pulley member m ofthe clutch from the fast member M, which is secured to the shaft m.

.At the same time a friction-pad (not shown,

but like that shown in the Towns andRaymond patent, No. 346,137,)carried by an arm extending from the rocking arm m is brought intocontact with the surface of the fast memher a of the clutch and stopsits rotation. The traveling block G upon the release of the detent-pawlis moved backward to its original position by a spring-operated drum IIOOsand a connecting-cord 0. (See Fig. 3.) This mechanism for moving thetraveling block G forward with an intermittent motion and backward witha continuous motion, and for automatically stopping the mech anism, ismore fully described in Patent No. 346,137, and need not be furtherdescribed here.

It is of course desirable to automatically start the nail-plate feedingand severing mechanism, though this is not essential. To effect thisIhave formed upon the nail-carrier slidebar D, which is operated by thecam (1 a shoulder or extension P, which has the inclined surface 1),(see Figs. 2 and 5,) and I have arranged to project into the path ofmovement of this projection or cam P the roll 1), carried at the end ofa lever p pivoted at 19 (See Fig. 5.) This lever is connected by the rod12" with the latch m (see Fig. 5,) and when the machine is at rest theroll bears against the under surface of the slide-bar D in front of theincline p, as represented in Fig. 2, and upon the starting of themachine the slide is moved inward or toward the head 0, bringing theincline p in contact with the roll and moving it downward, therebylifting the rod 19 and latch m upward and the latch from its engagementwith the lug or projection n on the lever m This permits the spring 19to draw the driven member of the clutch in contact with the fixedmember, and also permits the detent to fall so as to engage the teeth ofthe ratchet if, and its arm n to come under the section 72 of thelatch-bar, as represented in Fig. 5.

In operation the strip of connected fastenings is placed in the feedwayof the machine, so that the first fastening shall be in the throat ofthe machine, and upon the starting of the machine the plunger H is moveddownward, severing a fastening from the strip and forcing it through thethroat into the first of the holes g in the plate f The severedfastening then falls through the hole g and passage in the tubeconnecting said hole with one of the holes in the block f and comes torest in said last-mentioned hole. Upon the upward movement of theplunger H the strip is fed forward by the feed-pawl g another fasteningbrought into position in the throat, and the detent-pawl g brought intoposition behind the shank of the fastening, and the traveling block,with the nail-strip feeding and severing devices, moved forward by thefeed pawl m to bring the throat over the second of the holes g in theplate f". The plunger H is again moved downward, severing anotherfastening and feeding it to the second hole 1 from which it falls bygravity through the passage in the tube which connects that hole withanother hole in the block in which the fastening finally comes to rest.Upon the upward movement of the plunger H the tackstrip-feed pawl g ismoved outward to engage the shank of the first fastening in order, andthis intermittent operation of the tack-strip feeding and severingdevice and intermittent traveling movement of the block G carrying itcontinues until the throat g has been brought successively into linewith as many of the holes 9 as necessary to feed the tackstrip thenumber of nails or fastenings required, when the detent and feed pawlsare tripped, the mechanism stopped, and the traveling block G returnedto its original position.

I prefer that when an all-metal stripsuch as described in my saidpatent, No. 315,069, or other comb-strip is used-to make the throatsubstantially square or rectangular in crosssection and the plunger 11of similar shape in section. This will provide a nail or fasteninghaving a flanged rectangular head shaped substantially as represented inFig. 8, and when it is desired that these nails shall be delivered tothe driving devices, so that their greatest diameter shall besubstantially at a right angle to the line of the edge of the heel, Iform each tube f and the holes in the nailholder block f, nail-carriere, and the templet E, so that the nail is turned as it falls in the tubeenough to bring its head into the proper or desired position. It is thenheld in that position by the holes in the block f, nailcarrier, andtemplet until driven. This is accomplished by making holes in the blockf, nail-carrier, and templet oblong or rectangular in shape and of asize to prevent the turning of a fastening after it has been presentedthereto. The turning of the fastenings is done entirely by the tubes,the tubes having passages so shaped as to turn the nail upon a verticalaxis while it is dropping, which, as a rule, is not over a quarter of arevolution. This arrangement of nails in relation to each other so thatthe heads shall be uniformly arranged in relation to each other andadapted to have a predetermined relation to any given line is of coursedesirable only where the nails are driven so that their heads shall beleft exposed, and it is especially desirable in flush-nailing heels.

I do not wish to be understood as limiting myself to the specificmechanisms herein shown and described for feeding the comb or fasteningstrip and for severing the fastenings therefrom, as my present inventiondoes not relate particularly to the specific devices shown forperforming these functions, and any well-known or equivalent mechanismsfor those which I have shown for these purposes may be employed. Themechanism which I have described is probably as cheap and as effectiveas any which employs a combstrip of fastenings or a strip of fasteningsof similar character. The nail supplying and distributing devices, ofcourse, may be used with any other nail-driving devices than thoseherein shown without departing from the essential features of theinvention. I prefer that the throat g be somewhat increased in size fromits upper end downwardly, and that the passages g in the block IIO fandin the connecting-tubes f be enough larger than the throat to permitheaded fastenings to drop freely therein. I also consider that theintermittent movement of the distributer, so as to bring itsholes gsuccessively into position, or in register with the throat g, and so asto receive fastenings therefrom, whereby it is adapted to receivefastenings in successive order through the throat g and having a returnor a reverse movement, is the equivalent for the intermittent forwardmovement and return movement of the block G, and the mechanism forproviding the distributer with these movements in relation to thestationary block G would be similar in every material respect to thatemployed for moving said block.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States- 1.
